16 September problems flying in/out of DF

There's a short article in today's El Universal newspaper reporting that flights to/from Benito Juarez International Airport in Mexico City will be canceled between the hours of 9 a.m. to 12 noon because military aircraft will be participating in the Día de la Independencia festivities by making fly-overs. They will be occupying the airspace over the city during that period, so no other planes will be allowed in the sky. It is estimated that 80 to 100 flights will be affected.
